Sorry, but your numbers are quite wrong. India has 60-100 warheads and very effective misslile delivery systems. With problems in Afgan, Pakistan has been forced to move warheads from a forward deployed situation.
India also has much better "generalship."
Pakistan has not the viable nuke program which can mount even a basic assault on India. So they blew a half-megaton device in the side of a mountain. So what? With that, Chinese missle technology and a buck-fifty you too can get on the New York City subway.
Pakistan wouldn't even know what hit them the moment India attacks. Do not think for a minute that their vaunted "nukes" will survive even a limited air attack.
Pakistan, like the Taliban, made a choice. It was a poor one.
